Back when they pushed out the 15.7 that introduced the Super V. Resolution that ended up honking up peoples's display configurations. When I loaded 15.7 for windows 7 and Linux mint the screen was oversized and I couldn't see the lower windows task bar. They seemed to fix it with 15.7.1.
Its back again for windows 10 64 bit. Hopefully, there is a fix for this in their upcoming beta release for 15.8.
My configuration is a little unusual with a ASUS 22 inch monitor and Panasonic 40 inch TV, but I've had no problems for years until the more recent AMD updates.
